Skipper

• When chased by tuna or dolphins, the whole shoal leaps clear of the water and glides over the surface, a spectacle fishermen use to locate the predators.
• Its separate finlets, a trait it shares with the mackerels despite being unrelated to them, reduce turbulence when it swims fast.
• It is a key prey of tuna, marlin and seabirds in temperate oceanic waters.
• It has a row of finlets — small detached fins — behind the dorsal and anal fins, just like tunas, although it is not related to them: it is a case of convergence among fast-swimming fishes.
• When pursued by predators it leaps and skims over the surface in groups, a behaviour that has earned it its English name of skipper.
• It is a fundamental prey of the tunas, dolphins and seabirds of the open Atlantic, so its ecological role weighs more than its commercial value.
• Its beak is shorter and finer than the garfish's, and its two jaws are of similar length.
